Application led December 22, 1914. Serial No. 878,613.

:a point for each ink as in pens of this generalcharacter heretofore proposed.

Brieiy considered the invention resides in combining with a pen barrel rovided with suitable reservoirs for lthe di erent inks, a writing point which can be so arranged as to take ink from any reservoir.

In the embodiment herein disclosed a feed spoon is connected with each reservoir and the feed spoons not in use are retracted by a simple turning movement of one part of the barrel i`n`respect to another part. The pen point also is capable of retraction and the transposition of the point from register withV one feed spoon to another is effected in the relative turning movement of the two parts of the barrel.

Another special feature of the invention is thel provision of means for automatically wiping off the pen point so that it will be cleaned of one ink before being used with another ink.

Various other featureswill appear as the specification proceeds.

yThe accompanying drawing illustrates in concrete form a practical embodiment of my invention but it will be understood that various changes and modifications may be made ywithout departurefrom the true spirit and Iscope of the invention.

Figure 1, is a top view of a pen constructed in accordancewith and embodying the invention. Fig. 2, is a longitudinal sectional view of the same. Fig. 3, is a cross sectional view taken substantially on the plane of the line 8-8 of Fig. 2. Fig; 4, is a broken plan view of the guiding and supp'orting means for the feed spoons. Fig. 5, 1s a view of the lower section of the barrel.

The pen illustrated is for writing in two kinds of ink, say black and red, so two ink reservoirs, designated 7 and 8 are therefore provided in the barrel Vor body of the pen. These reservoirs are shown as of the selffilling type, in the form of rubber sacks which can be collapsed by means of the presser plates 9 and 10 having exposed fin-A ger pieces 11 and 12. y' l A single pen point 15 is provided and this is so mounted that it can be transposed tol draw ink from either reservoir. In the specific disclosure made herein this transporta tion is accomplished by retracting the pen polnt from operative relation to a feed spoon forvone kind of ink, relatively rotating the pen and reservoir to carry the retracted pen into register with a feed spoon for the other ink and then projecting the pen into position over the second feed spoon.

The pen is accordingly shown as carried by a holder 17 sl-idingly mounted within the lower Venol portion of the barrel and pro# vided with a stem 18 projecting up through a slot 19 in the barrel, said stem'having a finger cup 20 on its upper end by which the.

holder slide is operated. The relative ro'- ltative movement is obtained by making the barrel in two relatively rotatable parts, an

upper section 22 and a lower section 23, the upper section carrying the v' ink reservoirs and the lower section carrying the pen point.

The two feed spoons, are designated 25 and 26, the first being connected with the black ink reservoir 7 by a tube 27 and the other being similarly connected with the red ink reservoir 8 by a tube 28. These feed spoons are shown as arranged in the relative rotation of the barrel sections to be the one retracted into the barrel and the other projected into position `for use, such reverse movements being obtained by providing the spoons with lugs 29 and 30 engaging reversely inclined shoulders provided by the reversely inclined cam grooves 31 and 32 on the inner wall of the lower barrel section.

The feed spoons arevdisposed on opposite sides of a combined supporting and uiding bar 38, and they are shown as con ned to said bar by an encircling guide rin-g 34 which is secured to the lower end of the bar; The spoons are so shaped as to provide a space 35 between the back of the spoon and the inclosing guide ring through which the pen point can be projected.

The ink supply tubes 27 and 28 are preferably rigid so as to assist in guiding the feed spoons. Thus in the illustration each feed spoon is formed with a longitudinal bore end of itssupply tube,

the lit" being such that the spoon will slide lat' easilyl overl the tube.` vThe spoon is provided with a feed passage 38 leading off fro`m;thebo1e 37, preferably at ay point inthe@'barrely section4 and by being passed through. a supporting plug 40 closing the lower end ofthe-section. The supply tubes arealso supported inf this. plug, the inner f Yendsof the tubes. projecting far enough up intoffthefupper. barrel section for the necks of the :ink-sacks* tofbe slipped thereover.

I-ntl'ie construction` disclosedy the two sect-ionsfofjthe barrel are revolubly held to- 'f-'gether-'by means ofan abutment ring 50 'barrel;-section` and-has a screw threaded-enwhichJ-bearsfagainst the end of the lower ga'gementf overv the guide ring 34.

"T-of automatically clean the Vpen point of 2 "iloiI: have provided wiping material 60,

The gasket therefore constitutesfafsubstantial closure to Ythe feedr outlet Of-,thelspoon which is inthe re "tractedj'posit-ion 'y of nonuse. 451iv JAf further wiping effect is obtained in the present disclosure by providing a second body: of wiping material, shown in the form ofa 'ring 65` ofV leather o-r thelike, seated `ifinfan-annulangrooveway on the interior offV theiabutmentring 50at1 a point in Yadvanceffoftlie first body of wiping material; 5"From'fthelforegoing it 'will be evident that to@lchangey from "one ink to another,A it is merely'`Inecessaryto;A retract the pen point tof'a` position `^l\vhere -it4 will clear the feed spoonwithfwhich itfhas been coperating, than?t'relativelyv rotate the two barrel sectioirsaL half revolution and then to project 9* tliepe'npointf over-the new feed spoon with which'itfhasbeen brought into register by the relativeil'otary movement of the barrel sections. The cupfshaped finger piece 2O by which VVVthe penlpointjis retracted and proff'ff jected a'fveryfconvenient` rest for the "on'separatingthetwo ink reservoirs and itgrsfshownas supported therein by reason` y f 1"off1its.engagement'with the inner walls of` finger in writing and so is an advantage aside from its function ofshifting the pen. Dur-ing the retractive movement of the pen pointl the wiping.,r devices will automatically remove the surplus ink from the pen point. In the part rotary movement of'the relatively movable parts a rotary wiping action on the pen point will be produced and as the peny point is projected into position for use withfthe fresh feedy spoon a second longitudinal wiping effect will occur. This wiping of the pen point is sulicientordinarily to-remove all traces'of the last: ink used. y v

When a feedv spoon is retracted, the supply of ink thereto is automaticallv cut off by the closing of its supply tube and the possible escape of any ink remaining in thev f eed passage is prevented by thel substantiall closure of the said feed passage by the first wipingdevice 60. This wiping device also will act toprevent leakage of ink-if for any reason the ink supply should not be properly cut off. j

The parts, it will be noted areall ofvery simple and inexpensive construction and 2. In a fountain pen, a barrel made up.
